It has occurred to me several times that killer bees just aren't
as much problem with HACK 1.03 as with version 1.01.  In 1.03 you can
run away when you're in trouble.  The bees follow you (sometimes), but
they don't hit.  Previously, they'd follow you (closely) *and* hit.
After some looking at the code to 1.01 I found the problem.  One
section of code was changed to use an additional local variable which
checked to see if the monster was close to you.  However, the variable
was not updated when a multiple-move monster (B,A,k,o among others)
moved closer to you.  Thus these monsters didn't "know" they were
beside you and wouldn't try to hit you.

To make matters even easier for you, when one of these monsters went to move
again, the position you were at was considered inaccessible (because it was
occupied by something), so the monster often moved away!  This made killer
bees appear not to be able to track you even though they were right beside
you.  Needless to say, this made one of the most difficult monsters *much*
easier.

This bug fix restores the potency of killer bees (and other multiple-move
monsters).
